For the many fans who missed out on the chance to get their hands on tickets for Michael Jackson's This Is It tour, there is still hope. On Wednesday more tickets will go on sale for his 50-show run at the O2 arena.

A "limited" number of extra seats, originally held back while logistics for the production were worked out, are up for grabs for fans who have registered on his website. They will then be entered into a lottery system in order to buy the tickets.

When the first 750,000 tickets for Michael's residency tour went on sale in March, they sold put in a matter of hours.

The 50-year-old performer's first concert will take place on July 13, five days later than planned after it was announced the star needed longer for dress rehearsals.
